He means that you are using "assignment" operators, not "comparison"
operators, in most of your if statements. I.e.:
if (pp = NULL) {
This assigns NULL to the variable pp.
You likely want:
if (pp == NULL) {
which checks pp for equality to NULL.
Note, a way to get the compiler to complain about this style for you is
to reverse the two items in the if. Write it this way:
if (NULL == pp) {
or
if (5 == variable) {
Then, if you leave off an = sign, you'll get a compile error about
invalid assignment.
